JACOB WV. MILLER AND EDYVARD HUBER, OF MARION, OHIO.

PNEUMATIC STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 610,659, datedSeptember 13, 1898. Application filed May 25, 1898. $erial No. 631,662,(N d m and EDWARD HUBER, citizens of the United States, residing atMarion, in the county of Marion and State of Ohio, have invented certainnew and useful Improvements in Pneumatic Straw-Stackers, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to certain new and useful improvements inpneumatic strawstackers.

The object 01": .our invention is to provide for the utilization ofair-cnrrents to automatically operate a straw-deliverin g hood in apneumatic stacker for the purpose of delivering or directing thedischarging straw to different places.

Our invention also relates to details of construction hereinafterappearing, and particularly pointed out in the claims.

In the accompanying drawings, on which like reference-letters indicatecorresponding parts, Figure l is a side elevation of a portion of apneumatic straw-delivery pipe with our invention applied thereto, andFig. 2 is a plan view of the same.

The letter A represents a portion of a pneumatic straw-delivery pipe,such as usually employed in connection with threshing-machines where anair-blast is used for carrying the straw, chaff, dust, &c., passingthrough the thresher and discharging the same in any convenient place.Near the outer end of this pipe we mount a fan-casing B, secured to saidpipe by means of rivets O or in any other suitable manner. We haveprovided a fan D, having a shaft E, mounted in suitable bearings F, alsocarried by said fan-casing. On one end of said fan-shaft E is form ed orotherwise secured a worm G. This worm G meshes with a worm-driven gearH, mounted on a stud I, carried by a bracket J, extending from saidcasing B. A wrist-pin K extends from the upper face of the worm-drivengear H and has mounted thereon a pitman L. The other end of said pitmanL is connected with the crank M, which is rigidly connected with theadjustable parts of our hood P. Such hood consists of three sections aZ) c, the section a being secured to the casing B by means of rivets orbolts Q or in any other suitable manner,while the section'sb careriveted or otherwise secured to each other by means of rivets R, asclearlyshown in Fig. 1. These sections 1) and c are mounted on studs 0 Oto permit them to swing in a manner presently to apear. p Referringagain to the pitman, it will be seen that it has an up-and-down movementby reason of its joint S and also a sidewisc movement by reason of itsjointed connection with the crank M, as shown at T. This upand-downmovement permits the crank to be set in any one of the holes U in saidcrank, which is for the purpose of varying the swing ing movement of thehood P,aloove referred to.

The hood is operated by means of a portion of the air within the pipe A,which comes in contact with the arms cl of the fan D and causes the saidfan to rotate. This in turn drives the shaft E with its worm G and whichlatter meshes with and drives the wormdriven gear H and through'itspitman connection with the hood P causes the latter to oscillate backand forth across the opening in the end of said discharge-pipe. Thisoscillation back and forth of said hood directs the outward throw of thestraw. In order that the discharge end of said pipe may not be undulycontracted by said hood, we have provided a cutaway portion V in thepipe A, whereby the straw and air at all times may have ample room todischarge.

We regard ourselves as the first to operate a directing-hood so as todirect the discharging straw in different directions by the utilizationof air-currents actuating hood-operating devices and wish to lay broadclaim thereto accordingly.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. In a pneumatic straw-stacker, the combination with a pneumaticdelivery-pipe, of a hood, and its operating device actuated byaircurrents delivered by said pneumatic pipe, whereby said hood willdirect the discharging straw to different places.

2. In a pneumatic straw-stacker, the combination with a pneumaticdelivery-pipe, of a hood mounted thereon and adapted to direct thedischarging straw in different directions, and operating devices forsaid hood including a fan arranged to receive operating air-currentsfrom said pneumatic pipe.

3. In a pneumatic straw-stacker, the combination with a delivery-pipe,of a fan carried thereby and projecting within said pipe, a

hinged hood extending over the end of said delivery-pipe, and mechanismbetween said fan and said hood whereby when the fan is operated saidhood is also operated.

4. In a pneumatic straw-stacker, the combination with a delivery-pipe,of a fan having a shaft carried thereby and projecting within said pipe,a hood hinged to said pipe and adapted to extend across and be removedfrom the end of said pipe, and mechanism between said fan and said hoodwhereby when said shaft is operated said hood is also oper ated.

5. In a pneumatic stacker, the combination with a delivery-pipe, of afan having a shaft carried thereby and projectingtherein,a worm on saidshaft, a worm-driven gear meshing with and driven by said worm, aswinging hood hinged to said pipe, and a pitman connectin g said hoodand said driven gear whereby motion is transmitted from said gear tosaid hood.

6. In a pneumatic stacker, the combination with a delivery-pipe, of afan carried thereby having a worm on its shaft, a worm-driven gearmeshing with said worm, a hood hinged to said pipe, a crank secured tosaid hood, and a pitman connecting said driven gear and said crank andadjustable on said crank, whereby when the fan is driven the hood isvibrated across the outer end of said deliverypipe.

7. In a pneumatic stacker, the following instrumentalities: a pneumaticdelivery-pipe, a fan and its casing carried thereby, said fan extendingwithin said delivery-pipe, and having a shaft with a worm, a worm-drivengear meshing therewith andcarried by said oasing, a hood hinged to saidpipe, a crank secured to said hood and having a series of holes, a pitman having a Vertical joint-and a horizontal joint therein connectingsaid crank and said driven worm-gear and adapted to engage with any oneof said holes in said crank, substantially as shown and described.

In testimony whereof we affix our signatures in presence of twowitnesses.
